Wiseco 96-07 Mitsubishi EVO 85.5mm Bore 0.50mm Oversize 28.87 Comp Height Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty engine builds. The 85.50 mm bore size, which is 0.50 mm oversize from stock, is designed for the Mitsubishi 4G63 engine found in the EVO models. This specific bore size is crucial for achieving the desired displacement and compression ratio when rebuilding or modifying your engine.

Wiseco's Professional Series pistons are packed with features for improved performance and durability. They include precision ring grooves, anti-detonation grooves, and additional features to enhance ring seal. The pistons also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their ability to withstand severe duty applications. These pistons are engineered, forged, and machined in the USA.

This set includes four pistons, each with a 28.87 mm compression height and a 0.8661 inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance 4G63 engine, these Wiseco pistons offer a well-built foundation for serious power.
